On my test box with the Asus M3A32-MVP main board there is a
regression from 2.6.26 related to suspend, hibernation and
shutdown. Namely, if Wake-on-LAN is enabled with
'ethtool -s eth0 wol g', the box hangs solid during all of these
operations, while executing either sky2_suspend(), or
sky2_shutdown(). This patch fixes it for me.
